This article aims to establish the model of textual communication and its schema. To do this, we must identify the characteristics of textual communication, different from that of the oral, because the model of communication is usually done to show the structure of oral communication. Moreover, we must clarify the status text as '${\acute{e}}nonc{\acute{e}}$', that is to say product of the act of enunciation. The study of the text has now reached to achieve from the perspective of pragmatics, overcoming the structural point of view that dominates long text linguistics. And now, we need to enrich the theoretical basis of the pragmatics of text. Then the search of elements necessary to develop the model and pattern of textual communication can help to establish the elements used to form the theoretical basis. To clarify the characteristics of textual communication, we needed to explain the present communication by the position of reader and the point of view of textual reference. The schema that we proposed is not perfect, but there are still issues to think to complete it. For example, one must take into account the plurality of readers and reflect the relationship between interpretive texts in this schema, etc. This kind of problem is not only required to complete the schema but also to strengthen the basis of the theory of textual communication and the pragmatics of text.

This study examined the texts of the Late Joseon Dynasty's YEONJEONG GASA, whose authors are unknown, to list the contents of education which can be provided by conventional elements. Most existing discussions on expression education have focused on creativity. However, the perspective creativity based on the concepts of modern individualism and difference believes that creation can be done only by special professionals with inborn abilities and is likely to jeopardize the possibility and need of expression education to reduce the scope of expression education. On the other hand, conventionality has been related to "cliche" and "old-fashioned" and considered the counterpoint of creativity with lacking originality and aesthetical or educational valuelessness. Nevertheless, conventionality is valuable as cultural custom in that it is closely related to the contemporary culture, thoughts, and language. Also, it is the power that creates new text and induces sympathy in receivers. The Late Joseon Dynasty's YEONJEONG GASA by unknown authors include typicality of circumstances, schematism of emotion, and formula in conventionality. The positive aspects of conventionality - familiarity and intimacy - are the basis of sympathy and become the power that encourages the public to participate in creation and enjoyment within the frame of creativity. Ultimately, conventionality of YEONJEONG GASA allows learners to experience the pleasure of expression and has an important meaning for expression education as it provides them with the opportunity to perform expressions to extend sympathy.

최근 대하천사업을 통하여 낙동강에 총 8개의 다기능보가 설치되었으며, 이러한 하천 내 수공 구조물은 하천에 서식하는 어류의 이동과 군집의 변화, 유전적 단절, 서식처 변화와 같은 다양한 문제점을 유발할 수 있으며, 특히 어류의 산란기에는 하천의 유로를 따라 상류로 이동하거나 하류로 이동하는 회유성 어류들에게는 심각한 문제를 야기한다. 이러한 다기능보의 상 하류의 단절로 인한 문제를 해결하기 위해 낙동강 8개의 다기능보에 자연형 및 인공형 어도가 설치되었으며, 이를 평가하기 위한 어도의 유인효율에 대한 연구가 중요하다. 어류는 최대 유속이 발생하는 지점인 유심선에서 소상하려는 특성을 보이는데, 어도의 입구부의 유속이 중요하게 작용한다. 어도 입구부의 유속분포 및 수심에 따라 유인효율은 다르게 나타날 수 있으며, 2차원 수리해석을 통해 WUA를 산정함으로써 어도의 유인효율을 평가할 수 있다. 본 연구에서는 2차원 흐름해석 모형인 River2D를 이용하여 어류의 소상이 중요한 산란기를 기준으로 강정고령보의 가동보 운영실적을 이용하여 수리해석을 실시하였으며, 연구결과를 바탕으로 자연형어도의 유인효율을 평가하였다.

A numerical analysis based on two-dimensional, incompressible and compressible Navier-Stokes equations was carried out for double circular arc compressor cascade and the results are compared with available experimental data. The incompressible code based on SIMPLE algorithm adopts pressure weighted method and hybrid scheme for the convective terms. The compressible code with preconditioning method involves a upwind-biased scheme for the convective terms and LU-SGS scheme for temporal integration. Several turbulence models are evaluated by computing the turbulent viscous flows; Baldwin-Lomax, standard $\kappa$ -$\varepsilon$, $\kappa$ -$\varepsilon$ Lam. Bremhorst, standard $\kappa$-$\omega$, $\kappa$ -$\omega$ SST model.

Recently, the cause of flood damage has been the local torrential rainfalls rather than a total amount of yearly rainfalls. The domestic design code of drainage pump is being improved by considering the effect of local torrential rainfalls, while there is no consideration on the local torrential rainfalls in the domestic design code of bridge-deck drainage. Compared with the code of Federal Highway Administration in USA, no rational bases are specified in the domestic design code of bridge-deck drainage. This paper proposes the reasonable design guideline for bridge-deck drainage considering the effect of local torrential rainfalls.

본 연구에서는 한국 낙동강에 위치한 강정-고령보에 설치된 by-pass 어도의 유인효율을 유량 변화에 따라 살펴보고, 어도 유인효율을 극대화할 수 있는 최적의 본류 방류량을 산정하였다. 강정-고령보는 고정보와 가동보로 구성된 혼합식 보로 유량조절이 가능하며, 가동보의 조작에 따라 by-pass 어도 내의 유량이 결정된다. 유인효율의 지표로 목표어종의 HSC(Habitat Suitability Criteria) 지수에 기반한 WUA(Weighted Usable Area)를 삼았다. WUA는 평면 2차원 물리서식처 모형인 River2D를 활용하여 계산하였다. 또한 River2D로 계산된 유속장은 GPS Floater를 활용한 현장관측 자료로 검증하였으며, 어망을 이용한 월별 어류 모니터링 자료로 유인효율 평가의 타당성을 간접적으로 검증하였다. 결과적으로 본 연구 대상인 강정-고령보의 by-pass 어도에서 가장 효과적으로 목표 어류를 유인하기 위해서는 본류의 유량이 190 cms내외를 유지해야 한다. 특히 목표 어류인 모래무지가 봄철(4월~6월)에 산란기를 맞아 상하류로 이동하려는 경향을 띄므로, 이때 적절한 가동보 운영을 통해 본류 유량을 190 cms로 유지하는 것이 필요하리라 사료된다.

Non-geometric shapes in contemporary architecture was explained from the transcendental schema of Deleuze with his abstraction theory. In this explanation, the intensity, the movement and change and the sublime were suggested as the expressional elements of the transcendental abstraction related with the artistic sensation of architecture. First, the intensity as a power of sensation which acts to the body before the recognition of brain is mainly expressed with the movement of curved lines of architectural space. Second, the movement of change is expressed as the de-centralized and de-formalized nomadic curve as the line in architectural 'smooth space' which has unrestrained orientations. Third, the sublime is expressed in the hugeness, enormousness or sometimes uncanny in void space, which could be contradictively mixed with senses of displeasure and pleasure. The sublime feelings in architecture can be emerging by rationally overcoming the unpleasant senses of contradictive spaces in architecture or urban fabric. This study has explained those expressional elements with the architectural works of Steven Holl, Frank Gehry and Zaha Hadid.

Grus weathering mantles are widely distributed in Southern Korean Peninsula and are considered to be results of chemical weathering related to palaeoclimate milieu. This paper attempts to address this issue by CIA(chemical index of alteration). The climatic approach to the formation of grus mantles offers limited explanation of field occurrences, as these materials are widespread across climatic zones, from the humid tropics to cool temperate areas, although rates of grusification are likely to be influenced by climatic parameters. CIA values for granitoid weathering mantles in S. Korea are 50, which is the same of unweathered granitic rocks. Grus mantles in Korean peninsula show very low level in chemical alteration by CIA.

The database schema is assumed to be stable enough to remain valid even as the modeled environment changes. However, in practice. data models are not nearly as stable as commonly assumed by the database designers. Even though a rich set of schema change operations is provided in current database systems, the users suffer from the problem that schema change usually impacts existing application programs that have been written against the schema. In this paper, we are exploring the possible solutions to overcome this problem of impacts on the application programs. We believe that for continued support of the existing programs on the old schema, the old schema should continue to allow updates and queries, as before. Furthermore, its associated data has to be kept up-to-date. We call this the program independency property of schema change tools. For this property. we devise so-called program independency schema evolution (PISE) methodology. For each of the set of schema change operations in the relational schemas, the sketch of the additional algorithms due to the PISE compliance is presented in order to prove the comprehensiveness and soundness of our PISE methodology.
